Continue regular pinching of tips to maintain shape. Harvest outer leaves regularly. Remove any flower buds that appear. Maintain consistent moisture and warmth.
Peak Production

Harvest Tips
Begin harvesting when plant has 6-8 leaves (approximately 30-40 days). Pinch off leaves from the top, removing leaf pairs just above a leaf node to encourage branching. Harvest in morning after dew dries for best flavor. Regular harvesting promotes bushier growth and delays flowering. Can harvest continuously until frost in cool climates or year-round in zones 9-11 indoors. Never remove more than one-third of the plant at once.
